Problems solved by technology

[0003] However, the existing silicon-carbon anode material processing equipment has the following disadvantages: 1. Due to the relatively high particle size and hardness of the silicon-carbon anode material, high-strength crushing is required to complete the crushing operation. The existing processing equipment is not It meets the requirements of crushing, but it cannot be crushed with higher fineness; 2. After the silicon carbon negative electrode material is crushed, there are still large particles of raw materials, which need to be grinded again, but the existing secondary grind has grinding The fineness is not high, resulting in incomplete grinding, so that large particles of raw materials are mixed into it and discharged; how to further improve the effect of crushing and grinding of silicon carbon negative electrode materials is one of the problems we urgently need to solve

There is a vibrating screen assembly; the right side of the bottom box 1 is provided with a horizontally fixed grinding box 3, the middle of the grinding box 3 is provided with a horizontally fixed horizontal plate 4, and is located above the horizontal plate 4. In the grinding box 3, there is a For the grinding me...

Embodiment 2

[0041] Embodiment 2: In Embodiment 1, there is also the problem of inconvenient discharge of raw materials after pulverization and grinding. Therefore, on the basis of Embodiment 1, this embodiment also includes:

[0042] In the present invention, a first feeding shaft 5 placed laterally is arranged in the grinding box 3 under the horizontal plate 4 , and the right end of the first feeding shaft 5 is rotatably connected with the grinding box 3 and extends through the grinding box 3 . On the outside, in the grinding box 3, there are several first spiral blades 51 which are continuously screwed and fixed on the first feeding shaft 5. The right end of the first feeding shaft 5 is sleeved with a third driven pulley 54, which is located in the second feeding shaft 5. The outer side of the driving pulley 49 is sleeved with a third driving pulley 52 at the right end of the grinding shaft 41, and the third driving pulley 52 is connected with the third driven pulley 54 through the third...

Embodiment 3

[0044] Example 3: see Image 6 , in the present embodiment, the present invention also proposes a processing method of the lithium battery silicon carbon negative electrode material processing equipment that is convenient for grinding, including the following steps:

[0045] Step 1, add raw materials into the bottom box 1 through the feeding hopper 11, start the servo motor 12, control the motor shaft of the servo motor 12 to drive the first crushing shaft 13 and the first driving gear 15 to rotate synchronously, and drive the first driven gear through meshing. The gear 18 and the second pulverizing shaft 16 rotate in the reverse direction, thereby driving the first pulverizing reamer 14 to rotate in the forward direction and the second pulverizing reamer 17 to rotate in the reverse direction. Use, to pulverize the raw materials;

[0046] In step 2, the pulverized raw material falls onto the vibrating screen plate 22 along the partition plate 2 and the communication cylinder ...
